In my setup, I have a set of discovered elements, and for each one, I would like to configure a couple of parameters during the provisioning.
In the help, when editing a CI type, it is possible to configure a script for the update of the properties, but I wonder if this the correct place to achieve what I need. It seemed to be even more natural to use the Configuration section, but I wonder if there is a straightforward way to do such initial configuration.
There are two ways to perform actions after a Provisioning of Elements. As you are saying, you can configure a script to update properties (or any other actions that can only be done with an Automation Script).
The second way is to configure the 'Password Setup' in the Provisioning section of your CI Type. As the name says, it's initially meant to configure a password setup, but it can also be used to perform Parameters in a defined order.
You can configure the 'Password Setup' by going to the IDP Application, navigate to Admin > CI Types > Provsioning and click on the 'Advanced...' button for the CI Type you want. In the script that will open, you can click on 'Setup...'. You will get redirected to a screen where you can add Write parameters in a defined order. Save your CI Type and you're good to go!
